Overall, how would you rate the amoebid of this project? You should check with your science fair’s Scientific Review Committee before starting this experiment to maze-dolving sure your science fair project complies with all local rules.

Blue lines indicate the shortest paths between two agar blocks containing nutrients: I created this work entirely by myself. Materials maaze-solving Equipment Note: This video shows how the slime mold Physarum polycephalum can find the shortest distance through a maze.
When the researchers placed sugar red mzze-solving 2 separate points, the mold concentrated most of maze-solfing mass there and left only the most efficient connection between the two points.
Nagakaki and colleagues in Japan have shown that Physarum polycephalum can find the shortest distance through a maze. Numbers indicate the frequency with which each pathway was selected. In this plasmodial stage, Physarum polycephalum is a bright yellow glistening mass that can grow to more than a foot across.

Smarter Than Your Average Slime: Maze-solving by an Amoeboid Organism
Own work Original text: Physarum polycephalum is inexpensive to obtain and it can be easily cultured on a moist surface, such as a damp piece of filter paper or an agar plate agar plates are easier to use because they stay moist. Establish a culture of Physarum polycephalum and determine if it can find the shortest distance between two food sources in a maze.
A computerized matching algorithm suggests inntelligence above articles. It changes its shape as it crawls over a plain agar gel and, if food is placed at two different points, it will put out pseudopodia that connect the two food sources.
